MIL-M-38510-342 Microcircuits, Digital, Bipolar, Advanced Schottky Ttl, 4-Bit Binary Full Adders With Fast Carry, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, advanced Schottky TTL, 4-bit binary full adder microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

NOTE:

Input conditions at AO, 8O, A1, 81, and CO are used to determine outputs 8O and 81 and the value of the internal carry C2. The values at C2, A2, 82, A3, and 83 are then used to determine outputs 82, 83 and C4.
